Webhe sodium adsorption ratio (SAR) is commonly used as an index for evaluating the sodium hazard associated with an irrigation water supply. The SAR is defined as the square root of the ratio of the sodium (Na) to calcium + magnesium (Ca + Mg), i.e.: Ca Mg Na SAR + = (1a) where all cation measurements are expressed in millimoles per liter (mmol/L).

The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils. It is an indicator of the suitability of water for use in agricultural irrigation, as determined from the concentrations of the main alkaline and earth alkaline cations present in the water. It is also a standard diagnostic parameter for the sodicity hazard of a soil, as determined from analysis of pore water extracted from the soil.
